If you’re tired of pulling up and down the window bezel while flying, you might consider flying a Boeing 777X, according tomedia. This week, it was announced that some of the aircraft would be giving up the Electronic Dimmable Window (EDW) hood. Gentex, from Michigan, is understood to have made aircraft glass with a patented electrochromic gel sandwiched between two thin pieces of glass.
When a low-voltage current is applied to the gel through a conductive coating on the glass, the glass itself darkens. When the current is removed, the gel returns to its default transparent state.
This function can be controlled manually by the passenger by remote control of the cockpit.
These latest EDWs are said to be a major improvement on a model Gentex has previously built, as they are now darkening twice as fast as before and can be 100 times darker than before. In addition, it blocks 99.999% of the visible light from the outside at the maximum setting. Thanks to a thin film coating, the glass also blocks infrared and UV rays, keeping passengers cool and protecting them from harmful UV rays.
Since these windows will be available to customer airlines as optional add-ons, don’t expect to see them on all 777X aircraft. Right now, they’re on display at CES in Las Vegas.
